Abstract:According to the basic requirements of the development of new industrialization, the evaluation index system is constructed from four aspects: science and technology and information technology, economic benefits, resources and environment, and human capital. Using the improved TOPSIS method, take Tangshan, Hebei Province as an example, to evaluate the performance of new industrialization development in Tangshan from 2011 to 2020 and diagnose the obstacle factors. The results show that the total performance scores of new industrialization in ten years of Tangshan are above 0.9, and the overall level of economic benefit performance and human capital performance is high. The main obstacle factors affecting the performance of new industrialization in Tangshan are the same in ten years, and the obstacle degree from strong to weak is as follows: registered urban unemployment rate, number of research and development institutions, per capita green area of parks, rate of centralized sewage treatment, proportion of added value of new and high-tech industries in industries above designated size, number of patents granted, proportion of the number of regular institutions of higher learning in the total number of schools at all levels and of all types. On this basis, measures and suggestions are put forward with a view to providing reference for the development of new industrialization in Tangshan.
